Hide the Fighters you can never field
Last patch we started greying out Fighters you cannot pick, so your collection stopped looking full of holes. Now you can go one step further. A new toggle in the picker filters, remembered between matches, hides the Fighters that can never be fielded this match at all: wrong affinity, over the mana cap, ruleset-banned, off your commander's affinity, or blocked by rarity, edition, or foil rules. The only tiles it keeps greyed are the ones you cannot afford with your remaining mana right now, since those free up again the moment you drop a pick. Leave it off and nothing changes.
